It’s a collaboration between Rags to Riches, the Baths Community Trust’s resident upcycling project, and Sew La Tea Dough, a group dedicated to mending and making use of those old clothes at the back of the wardrobe.

Project manager Nadine Gorency has been helping volunteers to transform charity shop cast-offs into high fashion pieces and homewares since 2012, showcased at regular This Is Not a Craft Fair events.

She explained: “The point of Rags to Riches is quality upcycling, or 'extreme mending' - making garments of a high standard. We hope people can then see the value in things we'd otherwise throw away.

“It would have been the end of the line for many of the items on show. Take this tie dress - most of those ties still had charity shop tags on them, as we get donations out of the things which can’t be sold on.

“We’re adding value to items that are otherwise destined for landfill and now it’s something wearable, a one of a kind.

“We have a team of 20 makers and have also identified some emerging designers - like Thrifty Little, who makes 50s inspired clothes from bedsheets - so they’ll be showing their work on the day as well.”

The tiles of the Edwardian pool - a place volunteers are still working to restore after the place was closed by Glasgow City Council in 2001 - made a stunning backdrop for the 2014 catwalk, with models wearing everything from flower fascinators to newspaper kimonos wandering into the crowd.

Nadine promises even more theatrics on May 14, with the action taking place in the round and artists on board to design weird and wonderful sets.

But for Sew La Tea Dough's Donna Jamieson, the focus is as much on wearable, sustainable fashion as on high-end designs.

She said: “I think people know what upcycling is now - the term has been become more widely used - but occasionally the environmental side gets lost.

“People think it’s about creating these unique items, but you really have to do that with a view to reducing waste and impact on the environment. If you’re chopping an arm off a perfectly good shirt and attaching it to a skirt, then it’s not really helping anything.”

With 350,000 tonnes still heading for landfill in the UK every year, the point of monthly Sew La Tea Dough sessions is to help ordinary people darn a jumper to give it a new lease of life - and still wear it on an afternoon in the park.

Donna continued: “People are very welcome to come along and learn how to fix things They soon learn it’s about not relegating those items to the back of the cupboard.

“When you really love your clothes, you’re sad to get a hole in them. But if you know how to repair it then you can make a whole feature of it - and you soon grow to appreciate the workmanship involved in quality clothes and move away from throwaway fashion.

“If you can give those jeans or that handbag a new life then you’re keeping it in circulation that big longer, helping the environment and saving a piece of clothing you already love.”
